What this is

Record type 07. The production tubing in a wellbore: size as whole inches plus a fraction, the depth it is set to and where the packer sits.

How it is laid out

The Railroad Commission publishes this as Fixed-width ASCII. Columns are byte ranges with no separators, described only in a scanned record layout. We decode it into a table you can open anywhere. It has 9 columns and about 469.8K rows.

The columns you will most likely want:

  • api_county The three-digit county component of the API number. For offshore wells this is the nearest onshore county, not …
  • api_unique The five-digit well component of the API number. Unique only in combination with the county code.
  • segment_counter Sequence of this tubing string within the bore.
  • tubing_inches Tubing diameter, whole inches.
  • tubing_frac_num Numerator of the fractional part of the tubing diameter.
  • tubing_frac_denom Denominator of the fractional part of the tubing diameter.

…and 3 more, all documented on the full page.

What we add

Establish the completion configuration of a well, and check that a packer is set above a perforated interval as an injection permit requires.

  • Decoded out of the Commission's original format into something Excel opens.
  • Filterable before you download, so you can take one county instead of the whole state.

Worth knowing before you use it

Tubing size uses the same whole-plus-fraction encoding as casing: 2 7/8 inch is 2, 7 and 8 across three columns.
